概括
系统性β抑制剂 (BB) 可能会对眼球输液产生负面影响,特别是那些没有血管扩张特性的人. 然而,并非所有的BB都是同样有害的,需要进一步的研究.
科学领域:
- 眼科医生 眼科 眼科
- 心脏病学 心脏病学
- 医疗成像医学成像
背景情况:
- 高血压是各种心血管和眼部疾病的重要危险因素.
- 系统性抗高血压药物,特别是β抑制剂 (BBs) 已被广泛使用,但它们对眼部血液动力学的影响需要进一步研究.
- 光学连贯断层扫描血管学 (OCTA) 提供了一种非侵入性方法来评估眼球输液.
研究的目的:
- 评估高血压和全身抗高血压药物的影响,特别是β抑制剂 (BBs) 和其他药物,对眼球输液的影响.
- 使用OCTA对正常,可疑和眼的眼球输液参数进行比较.
- 调查具有血管扩张性质的BB是否与没有的BB对眼球输液有不同的影响.
主要方法:
- 一项涉及112名年龄在18-90岁的患者200只眼睛的横截面研究在三级眼科护理中心进行.
- 用前性招募了患有或没有青光眼的受试者.
- 使用OCTA测量了视神经周围毛囊输液和流量,以及表面视网膜层的斑点血管密度 (MVD).
主要成果:
- 使用全身BB的高血压患者与非高血压患者或服用非BB抗高血压剂 (NBB) 的患者相比,表现出显著较低的周周毛囊输液和黄斑血管密度 (MVD).
- 具有血管扩张性质的全身BB与与非高血压者和NBB用户相似的眼球 perfusion 参数相关.
- 与非高血压药物相比,没有血管扩张性质的BB与显著降低的周围毛囊输液和MVD有关.
- 多变量分析表明,年龄的增加是唯一与周和黄斑 perfusion 减少显著相关的因素.
结论:
- 虽然单变量分析表明系统性BB用户的眼膜 perfusion 较差,但多变量分析显示在考虑其他因素时,类似的 perfusion 参数.
- 具有血管扩展性质的全身BBs与没有的系统BBs相比,显示出更好的眼 perfusion.
- BBs对眼球输液的有害影响在所有药物中并不均; 血管扩张等特定特性起着至关重要的作用.
- 需要进一步进行经过精心控制的前性研究,以最终评估带有和没有血管扩展性质的BBs对眼球输液的差异性影响.

Open Angle Glaucoma: Treatment
453
In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.

Glaucoma: Overview
574
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...

Angle Closure Glaucoma: Treatment
505
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...
